Moonee Valley Council lodged Supreme Court documents challenging the east west link project on Thursday.

The council’s case is based on why the state government changed the project and challenges the legality of the decision and the process followed.

Deputy mayor Cam Nation said the late and “surprise” changes to the project announced by Planning Minister Matthew Guy in October would have “devastating impacts” on the municipality.

“Council has initiated a Freedom of Information request to obtain the project’s plans and details to determine if there was sufficient justification for the last minute changes to the design, which added a complex network of elevated roads next to the Flemington Housing Estate and along Moonee Ponds Creek”, Cr Nation said.

Major changes to the project included a new four to five lane road through Debneys Park and a widened Ormond Road off ramp and new Brunswick Road on ramp.
